To all whom it may concern:

Be it known that we, L. M. RUMSEY and W. P. SMITH, of St. Louis, in thecounty of St. Louis, and State of Missouri, have invented a new anduseful Improvement in Well-Pipe Driver; and we do hereby declare thatthe following is a full,clear, and exact description thereof, which willenable those skilled in the art topmake and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates tofimportant improvements inmachinesfordriving-pipe, .in the process of cou,- structing drive-wells, forobtaining water, and for other purposes of a similar nature; and

It consists in the construction and larrangement of the parts of themachine, as hereinafter described.

In the accompanying plate of drawings- Figure 1 represents an elevationof the driver, partly in section.

Figure 2 is a detached view of the drop, or hammer, looking iiom thelinex a: of iig. l.

Figure 3 is a view of the base-guide, detached, looking from the line yy of iig. 1.

Similar letters of reference indicate corresponding parts.

A is the foundation, or platform by which the machine is supported.

B B represent two uprights, supported on the platform, which form ways,or guides for the cross-head of the hammer, and also for the follower.

C is the drop-hammer, which is guided on the ways B B' by the cross-headD.

E represents the drive-head, which is connected with the pipe-guide F.

This head is provided with a chamber, which is filled with wood, as seenat g, to receiveA the blow of the hammer, the face of which hammer isalso of wood,

as seen at h.

'i is a collar on the drive-head. v J is the follower, through which thepipe-guide F passes.

The follower is a cross-head, guided by the uprights, the same as D.

K is a stirrup, which is attached to the follower by staples, orshank-eyes, as seen in the drawing.

This stirrup, at its top end, is a plate, with au orice suiciently largeto admit the top of the drivehead, so that the plate of the stirruprests on the co1- lar i, as seen.

L is the base-plate, (seen in iig. 3,)v through which the pipe passes,and by which the pipe is guided.

This guide-plate L is held in position hy the. uprghts, and restsloosely on the bed-plate N, which is secured to the foundation-A. y Y

O O represent braces, or stay-rods, (two or more in number,) which areattached to the transverse cappiece P and to the foundation of the machie.

This cap-piece has a mortise, in which there is a pulley, as seen at q,in dotted lines, and the upper end of the upright guide B is alsoprovided with a pulley, as seen at R.

S is the rope which is attached to the hammer, and passes over thesepulleys, as seen in the drawing.

Instead of wood in the top of the drive-head, and.` l

for the face of the drop, or hammer, any other suitaf ble yieldingsubstance may be used.

The plate L keeps the pipe in an upright position when being driven,while the upper 'end of the guidepipe F is held in position by thefollower and stirrup, l We claim as new, and desire to secure by'Letters Patent- The stirrup K, in combination with the follower J andadjustable drive-head E, provided with an internal screw-thread, tolreceive the end of the pipe F, as herein described,'for thepurpose'specied.
